An elongated coin (also known as a pressed penny or smashed penny) is a coin that has been flattened or stretched, and embossed with a new design. Such coins are often used as commemorative or souvenir tokens, and it is common to find coin elongation machines in tourism hubs, such as museums, amusement parks, and natural or man-made landmarks .
An improperly cleaned Indian Head cent from 1900. Note the wear present, as well as tarnished areas on the "brilliant red" surface. Coin cleaning is the controversial process of removing undesirable substances from a coin's surface in order to make it more attractive to potential buyers.
A copper-zinc voltaic pile. The penny battery is a voltaic pile which uses various coinage as the metal disks (pennies) of a traditional voltaic pile. The coins are stacked with pieces of electrolyte soaked paper in between (see diagram at right). The penny battery experiment is common during electrochemistry units in an educational setting.
The unique composition of the coin (low-grade steel coated with zinc, instead of the previously 95%-copper-based bronze composition) has led to various nicknames, such as wartime cent, steel war penny, zinc cent and steelie. The 1943 steel cent features the same Victor David Brenner design for the Lincoln cent which had been in use since 1909.
This leads to the possibility of smelters taking coins and melting them down for the scrap value of the metal. Pre-1992 British pennies were made of 97% copper; but as of 2008, based on the price of copper, the value of a penny from this period is 1.5 new-pence. Modern British pennies are now made of copper-plated steel.
Canada's elimination of the penny, however, rounds cash transactions both up and down. [24] The paper stated that rather than eliminate the penny, it would make more sense to change the composition of the penny to a cheaper metal than zinc if the costs of zinc do not come down and there continues to be a significant loss per penny.
The Lincoln cent (sometimes called the Lincoln penny) is a one-cent coin that has been struck by the United States Mint since 1909. The obverse or heads side was designed by Victor David Brenner , as was the original reverse, depicting two stalks of wheat (thus "wheat pennies", struck 1909–1958).
